Study on Influence of Blade Number on Aerodynamic Noise of Half-ducted Propeller Fans for Packaged Air-conditioners

Flow fields in 2-blade and 4-blade half-ducted propeller fans for the outdoor units of air-conditioners were calculated with large eddy simulation based on finite element method with the aim of investigating the influence of blade number on aerodynamic noise. We confirmed that the tip vortex had a g...
